Elusive Attenborough echidna rediscovered in Indonesia

An elusive echidna feared extinct after disappearing for six decades has been rediscovered in a remote part of Indonesia, on an expedition that also found a new kind of tree-dwelling shrimp.

The Zaglossus attenboroughi, a kind of long-beaked echidna named for famed British naturalist David Attenborough, had last been seen in 1961.

U.S. surgeons perform world's first whole eye transplant

A team of surgeons in New York has performed the world's first transplant of an entire eye in a procedure widely hailed as a medical breakthrough, although it isn't yet known whether the man will ever see through the donated eye.

The groundbreaking surgery involved removing part of the face and the whole left eye -- including its blood supply and optic nerve -- of a donor and grafting them onto a lineworker from Arkansas who survived a 7,200-volt electric shock in June 2021.

U.S. approves first vaccine against chikungunya virus

Washington (AFP) - US health authorities on Thursday approved the world's first vaccine for chikungunya, a virus spread by infected mosquitoes that the Food and Drug Administration called "an emerging global health threat." The vaccine, developed by Europe's Valneva which will be marketed under the name Ixchiq, was approved for people 18 and over who are at increased risk of exposure, the FDA said. Ixchiq's green-light by the US drug regulator is expected to speed the vaccine's rollout in countries where the virus is most prevalent. Chikungunya, which causes fever and severe joint pain, is gen...

Blue Origin’s new crane at Port Canaveral another piece to future launch puzzle

PORT CANAVERAL, Fla. — Blue Origin has staked out its space at Port Canaveral, right next to SpaceX, with a tower crane for eventual rocket booster recovery operations.

Now the company just needs to launch one to put it to work. The crane arrived at the port as cargo from Germany in October adding another puzzle piece to Jeff Bezos’ plans to send up its heavy-lift New Glenn rocket from Cape Canaveral Space Force Station’s Launch Complex 36.

Republican spending bill implodes over 'embarrassing' birth control spat

Another government funding bill from Republicans was pulled on Thursday morning after many leaders refused to back several pieces of the bill, including one aimed at overturning a law that barred companies from discriminating against employees who use birth control.

The birth control plank was just one of dozens of amendments that were added to the bill from Republican lawmakers, as House Speaker Mike Johnson (R-LA) pledged to pass the budget by the Nov. 17 shutdown deadline.

How animals get their skin patterns is a matter of physics

Patterns on animal skin, such as zebra stripes and poison frog color patches, serve various biological functions, including temperature regulation, camouflage and warning signals. The colors making up these patterns must be distinct and well separated to be effective. For instance, as a warning signal, distinct colors make them clearly visible to other animals. And as camouflage, well-separated colors allow animals to better blend into their surroundings.

In our newly published research in Science Advances, my student Ben Alessio and I propose a potential mechanism explaining how these distinctive patterns form – that could potentially be applied to medical diagnostics and synthetic materials.

Over the past six years, governments proposed launching over one million satellites

In September 2021, Rwanda announced that it was planning to launch over 300,000 satellites. Three months later, a Canadian company, having previously launched two dozen CubeSats, said it would launch an additional 100,000. Then, a French company did likewise. And SpaceX, which has already launched around 5,000 satellites, now has plans for over 60,000 more.

There are currently only about 8,000 active satellites in orbit. What’s going on?

Endangered Galapagos tortoises suffer from human waste: study

Turtles of the species Chelonoidis porteri ingest plastic in and around urban centers on the island of Santa Cruz, according to the study by the Charles Darwin Foundation, which is dedicated to conservation efforts in the Galapagos.

Researchers analyzed 5,500 samples of fecal matter in areas where tortoises come into contact with human activity, and found 597 pieces of debris of human origin -- mostly plastic, but also glass, metal, paper, cardboard and fabric.

He was too sick for a lung transplant. Then, doctors held his heart in place with breast implants

CHICAGO — Before David “Davey” Bauer made history at Northwestern Medicine for a double lung transplant assisted by a pair of DD breast implants, he considered himself a fairly healthy guy. Bauer, 34, spent his hours off from his landscaping job in De Soto, Missouri — near St. Louis — golfing, snowboarding and skateboarding. Cigarettes, he thought, were the only negative. A former smoker who went through a pack a day for four years, Bauer switched to vaping in 2014. “I thought it seemed like a safer alternative,” Bauer said. “In hindsight, it seems like I should have just quit sooner ... it’s ...

Weedkillers are hitting Missouri and Illinois forests. And they’re killing trees.

NASHVILLE, Illinois — Agricultural weedkillers are slowly killing trees across Missouri and Illinois, scientists, state workers and landowners say. Landowners say 200-year-old oaks have gotten sickly. State conservation workers are documenting trees with curling leaves and forests with thinning canopies. Scientists have studied hundreds of trees and found widespread evidence of chemicals in their leaves. The signs are spreading across the region, from farms to conservation areas to some of Illinois’ largest forests. Many affected trees have already died or been logged, and experts and property...

‘Miniature’ mountain creature — with ‘squeaker’-like call — discovered as new species

A “squeaker”-like sound pierced the air of a mountain forest in Rwanda.

The call came from a “miniature” creature sitting on the forest floor. Scientists found the source of the sound — and discovered a new species. J. Maximilian Dehling ventured into the Nyungwe Forest on several trips between 2010 and 2018, he wrote in a study published Oct. 23 in the journal Diversity.

Vampire viruses prey on other viruses − and may hold the key to new antiviral therapies

Have you ever wondered whether the virus that gave you a nasty cold can catch one itself? It may comfort you to know that, yes, viruses can actually get sick. Even better, as karmic justice would have it, the culprits turn out to be other viruses.

Viruses can get sick in the sense that their normal function is impaired. When a virus enters a cell, it can either go dormant or start replicating right away. When replicating, the virus essentially commandeers the molecular factory of the cell to make lots of copies of itself, then breaks out of the cell to set the new copies free.

Your mental dictionary is what makes you unique − how your brain stores & retrieves words

The days of having a dictionary on your bookshelf are numbered. But that’s OK, because everyone already walks around with a dictionary – not the one on your phone, but the one in your head.

Just like a physical dictionary, your mental dictionary contains information about words. This includes the letters, sounds and meaning, or semantics, of words, as well as information about parts of speech and how you can fit words together to form grammatical sentences. Your mental dictionary is also like a thesaurus. It can help you connect words and see how they might be similar in meaning, sound or spelling.
